Taxonomy Structure Methodology ① l Definition of the concept itself is separated from the relationship between concepts • The structure is composed of “Taxonomy for internal use” (concept itself defined use with schema, label link and reference link) and “Reporting Taxonomy” (relationships Taxonomy between concepts defined using presentation link , calculation link and definition link). l Each account varies according to FSI business type • Taxonomy for internal use is composed of a common taxonomy for all financial institutions and a delta taxonomy according to the business type. l Ease of maintenance is of primary consideration • The taxonomy for internal use has a structure which maps the roles of each type of maintenance engineer to enable job allotment. l Applicability to other reports • The methodology of separating the common and delta taxonomy is applicable, for example, to the annual business report, for changes to due date and in reporting data types. 12 © 2004 Bank of Japan

3.Test summary • Test results and summary of Phase 2 • Evaluation of Phase 2 by test participant FSIs 13 14 © 2004 Bank of Japan
Results and summary of Phase 2 pilot project - Part 1 (July) • Created the taxonomy of the monthly accounting table using Spec. 2. 0 (Bank of Japan) • Able to generate an instance in XBRL format without any problem using Excel table which includes the monthly accounting table (FSIs) • Received the data and could re-create the table (Bank of Japan) Understanding of XBRL penetrates to a broader range of FSIs Phase 2 pilot project - Part 2 (Sept. ) • Created the taxonomy for the annual business report using Spec. 2. 1 (Bank of Japan) • Able to generate an instance in XBRL format without any problem using Excel table which includes the annual business report (FSIs) • The data was received online and could re-create the table (Bank of Japan) Both the technical and operational usefulness of XBRL is confirmed Importance of validation Need for reorganization to accept XBRL data Study of storage and re-use of XBRL data Expectations for practical use 15 © 2004 Bank of Japan
Response to the Phase 2 questionnaire ① Summary of response (replies from 31 participating FSIs) - XBRL name recognition ・・・ Approx. 80% - Felt the need to study XBRL through the pilot project ・・・ Approx. 60% Expanding recognition of XBRL - Main points where FSI felt the benefits of XBRL: ① Enables data validity check ② Enables the addition and checking of notes to the items ③ Enable verification of the link documents such as item definition etc. 16 © 2004 Bank of Japan
Response to the Phase 2 questionnaire ② Reasons for participation in the pilot project (i) Study of values and issues --- Analyzes and evaluates what type of actual value and impact can be obtained through the use of XBRL (ii) Understanding and confirmation --- Able to learn about XBRL (iii) Ease of participation --- Conditions to participate were simple, and so participation was easy. (iv) Experience to use the tools --- Wanted to use the XBRL conversion tools 17 © 2004 Bank of Japan
Response to the Phase 2 questionnaire ③ Businesses where XBRL could be applied in the future - The kinds of businesses that would be able to use XBRL • Data storage and analysis • External report generation • Loan bsiness • Auditing • In-house account • In-house data collaboration • Public relations settlement t 18 © 2004 Bank of Japan
